| description | To provide an optical fiber which can solve a problem in wettability, a problem in coagulation and a problem in phase separation in production of a polymer clad optical fiber, and a method for producing the same.SOLUTION: An optical fiber 100 includes a glass core 101 and a polymer clad 102 formed in the periphery of the glass core, in which the polymer clad contains a mixture of a polymerizable composition and a silane coupling agent and a fluorine-based ultraviolet cure resin, when the total weight of the mixture is 100 pts.wt., the mixture contains 5-95 pts.wt. of the silane coupling agent, a refractive index after ultraviolet cure of the fluorine-based ultraviolet cure resin alone is in a range of 1.350-1.420, and a component derived from a silane coupling agent concentrates on a range of 20 μm or less in the polymer clad from the interface between the glass core and the polymer clad.SELECTED DRAWING: Figure 1A
【課題】ポリマークラッド光ファイバの製造における濡れ性の問題、凝集の問題、及び相分離の問題を解決することのできる光ファイバ及びその製造方法を提供する。【解決手段】光ファイバ１００は、ガラスコア１０１と、ガラスコアの周囲に形成されたポリマークラッド１０２とを備え、ポリマークラッドには、重合性組成物及びシランカップリング剤の混合物と、フッ素系紫外線硬化樹脂とが含まれ、混合物の全重量が１００重量部とすると、混合物はシランカップリング剤を５〜９５重量部含み、フッ素系紫外線硬化樹脂単独での紫外線硬化後の屈折率は１．３５０〜１．４２０の範囲にあり、ガラスコアとポリマークラッドとの界面からポリマークラッド内２０μｍ以下の範囲にシランカップリング剤に由来する成分が集中している。【選択図】図１Ａ |
